According to a review of the 1st edition by Frank L. Schick, the listings were pulled from PW's weekly "Mass Market" feature. Schick noted it was "the first and only exclusive American paperback bibliography to date." This publication would be the ideal source finding bibliographical information about many of the paperbacks on this site, but it is only available in research libraries (WorldCat record). University of Michigan has a nearly-complete print set that has been scanned by Google and made available on HathiTrust.

The publication frequency for this title varied (originally it was published three times a year, switching to semi-annual shortly thereafter, in the 1960s nine annotated monthly "Month Ahead" issues were published to cover the next month's paperback publications, and it eventually settled on spring/fall issues in the early 1970s.) There were three sections with different arrangements: (1) by author, (2) by subject, and (3) by title. Each paperback listed had the following information: Author, Title, Publisher, Price Series, Series # and whether it was a reprint or original.

There's an amusing review of Paperbound Books in Print in the Feb. 15, 1970, NEW YORK TIMES BOOK REVIEW, written by Marvin Kitman, at p. 31, https://timesmachine.nytimes.com/timesmachine/1970/02/15/issue.html:

The book is weighty, solemn and, in all honesty, not as functional as a plumber's supply manual. For 14 years, R. R. Bowker has been wrestling with the problem of how to keep this monster up to date. They have even gone to the computers, which accounts for the growing number of inexplicable double listings. For some reason, this book still doesn't seem to settle the question of whether a paperback is in print or not.

The problem may be that the reference work is poorly thought out. The way it is organized now there is too much room for second guessing with three separate lists (title, author and subject). While this may capture the spirit of the chaos of paperback publishing, it is too confusing for the average book buyer. Instead of the organizing principle of the railroad timetable, why doesn't Bowker use the telephone-company directories as a model.

As an experiment I would try publishing a master list of books in print mixing authors and titles indiscriminately. If a person can't remember either the name of the book or its author, he can't be too serious about buying a book anyway.

See the section following for a complete publication history of Paperbound Books in Print, in its many, many variations.

Publication History of Paperbound Books in Print

In the following timeline, full dates in parentheses (month, day, year) refer to issues of Publishers' Weekly in which the relevant issue of PBIP was recorded.

Bowker initially published PBIP three times a year. The subscription rate was $2 for three issues a year:

    • Summer 1955, no. 1 (May 21, 1955) — 4500 titles, 100 pp., $1

    • Fall 1955, no. 2 (Oct. 29, 1955) — 5000 titles, 117 pp., $1 (LC Virtual Card Catalog entry)

    • Spring 1956, no. 3 (Mar. 24, 1956) — 5000 titles, 133pp., $1

Bowker changed PBIP to semi-annual with Volume 2. The subscription rate changed to $3 for two issues a year. Spring-summer/summer issues were published in June and fall-winter/winter issues in November:

With Volume 5, Bowker added interim editions to be published in March and September to supplement the spring/winter editions published in June and November:

Bowker switched to 4 full issues a year with the Winter 1960-61 issue (see below for more information on Selected Paperbacks):

    • Winter 1960-61, vol. 5, no. 5 (Feb. 27, 1961) — 11,000 titles, 416 pp., $2, Olga Weber ed. (LC Virtual Card Catalog entry)

    • Spring 1961, vol. 6, no. 1 -- 11,500 titles, Olga Weber ed. (LC Virtual Card Catalog entry)

    • Subject Index to PBIB — 130pp., $2, early April, 1961?

    • Summer 1961, vol. 6, no. 2 (July 31, 1961) — 13,000 titles, 448 pp., $2, Olga Weber ed. (LC Virtual Card Catalog entry)

    • Selected Paperbacks, Fall 1961 — 64 pp., available in quantity lots at $.16 each for 100 copies, late September

    • Winter 1961-62, vol. 6, no. 4 (Mar. 5, 1962) — 14,700 titles, 590 pp., $3, Olga Weber ed.

    • Spring 1962, vol. 7, no. 1 (Apr. 16, 1962) — 15,700 titles, 640 pp., $3, Olga S. Weber ed. & Anne Cserr asst. ed.

    • Summer 1962, vol. 7, no. 2 (July 30, 1962) — 16,600 titles, 680 pp., $3, Olga S. Weber ed., Nancy Paige asst. ed., & Anne Cserr managing ed.

    • Fall 1962, vol. 7, no. 3 (Oct. 15, 1962) — 17,900 titles, 744 pp., $3.45, Olga S. Weber ed.

    • Winter 1962-63, vol. 7, no. 4 (Jan. 14, 1963) — 19,500 titles, 784 pp., $3.45, Olga S. Weber ed. & Anne Cserr managing ed.

Bowker changed publication again, moving to three cumulative indexes as PBIP a year, with monthly supplements appearing on the 15th of every month; the spring and summer 1963 PBIP issues came out as previously announced, with the new Month Ahead supplements beginning July 15, 1963 (with an August 1963 dateline); starting with the fall 1963 cumulative issue issue, the cumulative index issues were bound together with that month’s supplement:

    • Spring 1963, vol. 8, no. 1 (May 13, 1963) — 21,800 titles, 440 pp., $4.00, Olga S. Weber ed. & Anne Cserr managing ed.

    • Summer 1963, vol. 8, no. 2 (July 8, 1963) — 22,800 titles, 448 pp., $4.00, Olga S. Weber ed.

    • The Month Ahead, August 1963, vol. 8, no. 3 — July 15, 1963

    • The Month Ahead, September 1963, vol. 8, no. 4 — August 15, 1963

    • Cumulative Issue, October 1963, vol. 8, no. 5 — 23,600 titles, September 15, 1963

    • The Month Ahead, November 1963, vol. 8, no. 6 — October 15, 1963

    • The Month Ahead, December 1963, vol. 8, no. 7 — November 15, 1963

With Volume 9, PBIP for the first time had 12 monthly issues, January to December. This publication schedule, with 3 cumulative issues appearing in February, June, and October, and a supplement appearing every month, continued through volume 16 in 1971. Here are the volumes and years:

    • Volume 9 (1964), Volume 10 (1965), Volume 11 (1966), Volume 12 (1967), Volume 13 (1968), Volume 14 (1969), Volume 15 (1970), Volume 16 (1971).

Bowker changed the schedule yet again, in March 1972 switching to two giant clothbound 8 ½ x 11 cumulative volumes a year. Single volumes were $18.95, and an annual subscription was $32.50:

Barely a year later, Bowker changed the publication schedule to three times a year, with issues published in November, April, and July. Single copies were $19.50, and an annual subscription was $52.50.

But wait! Even though Bowker advertised PBIP with an image showing July 1974 on the spine of that volume, a later ad showed it had Summer 1974 on the spine and front cover. So with the Summer 1973 issue, the title was released in Summer, Fall, and Spring editions:

And yet . . . still more changes. Bowker next moved to issuing a single base volume per year, to be published December 30, with two supplements, on May 15 and September 15. Here's how this scheme was summarized in an ad in PW (Nov. 18, 1974, at 42):

The base volume, PAPERBOUND BOOKS IN PRINT 1975, contains complete finding and ordering information for more than 122,000 paperbacks currently available in the United States. The May Supplement will list all new titles, new editions, and o.p.'s as well as price and other changes occurring since the base volume was published. The September Supplement will completely replace the May supplement—cumulating all changes occurring since PAPERBOUND BOOKS IN PRINT 1975 was issued.

The new price was $54.50 for an annual subscription. Note: the Nov. 18, 1974, ad shows all three volumes in hardcover, but an ad from Sept. 8, 1975, shows the next year's cumulative in hardcover and supplements in softcover. Anyway, here's the new schedule:

Never say consistency was a virtue to Bowker. Starting in 1978, they changed the dang publication schedule PBIP again! The new scheme involved two base volumes, in January and October. Thus the publication was back to being semi-annual with no supplemental volumes. Single volumes could be purchased for $37.50 or both on a subscription basis for $62.50:

    • Spring Volume 1978

    • Fall Volume 1978

The single volume price increased to to $39.50 and the subscription to $67.50 with the 1979 volumes:

    • Spring Volume 1979

    • Fall Volume 1979

The subscription price increased to $70.00 with the 1980 volumes:

    • Spring Volume 1980

    • Fall Volume 1980

The single volume price increased to to $43.00 and the subscription to $75.00 with the 1981 Spring and Fall volumes, each of which, at no extra cost to subscribers, Bowker decided to split into two volumes themselves, the first volume containing author and title indexes and the second subject and publisher indexes:

    • Spring Volume 1 1981

    • Spring Volume 2 1981

    • Fall 1981 Volume 1

    • Fall 1981 Volume 2

In 1982, Bowker brought still more changes to PBIP. For one thing, the Spring and Fall volumes went from 2 volumes to 3 volumes (an author index in the first volume, a title index in the second volume, and a subject index for non-fiction titles and a Directory of Publishers and Distributors in the third volume). Each 3-volume set was $55.00, while a subscription for all 6 volumes was $97.50:

    • Spring 1982 Volume 1

    • Spring 1982 Volume 2

    • Spring 1982 Volume 3

    • Fall 1982 Volume 1

    • Fall 1982 Volume 2

    • Fall 1982 Volume 3

Not to be outdone by its own complexities, Bowker decided to release Books in Print, Paperbound Books in Print, and the new Mass Market Paperbound Books in Print on microfiche beginning in April 1982 (see Books in Print to Be Issued on Microfiche, PW, Mar. 12, 1982, at 13). BIP was scheduled to be updated quarterly, while the paperbound editions were to be updated monthly. The subscription rates were: $195 for BIP, $295 for PBIP, and $50 for MMPBIP.

For 1983, each 3-volume set was $69.50, and a whole year's worth of PBIP was $119.50:

    • Spring 1983 Volume 1

    • Spring 1983 Volume 2

    • Spring 1983 Volume 3

    • Fall 1983 Volume 1

    • Fall 1983 Volume 2

    • Fall 1983 Volume 3

For 1984, each 3-volume set was $75.00, and a whole year's worth of PBIP was $125.00:

    • Spring 1984 Volume 1

    • Spring 1984 Volume 2

    • Spring 1984 Volume 3

    • Fall 1984 Volume 1

    • Fall 1984 Volume 2

    • Fall 1984 Volume 3

For 1985, each 3-volume set was $85.95:

    • Spring 1985 Volume 1

    • Spring 1985 Volume 2

    • Spring 1985 Volume 3

    • Fall 1985 Volume 1

    • Fall 1985 Volume 2

    • Fall 1985 Volume 3

For 1986, each 3-volume set was $110 (or $104.50 if you had a standing order):

    • Spring 1986 Volume 1

    • Spring 1986 Volume 2

    • Spring 1986 Volume 3

    • Fall 1986 Volume 1

    • Fall 1986 Volume 2

    • Fall 1986 Volume 3

For 1987, each 3-volume set was $119.95 (or $113.95 if you had a standing order):

    • Spring 1987 Volume 1

    • Spring 1987 Volume 2

    • Spring 1987 Volume 3

    • Fall 1987 Volume 1

    • Fall 1987 Volume 2

    • Fall 1987 Volume 3

Bowker got fancy with their pricing in 1988. There was a special offer to buy the Spring 1988 edition at full price of $129.95 and get the Fall 1988 edition for $99.95. You could get the Spring 1988 edition for $123.45 if you had a standing order. The price went up to $139.95 for the Fall 1988 and Spring 1989 editions (standing order price: $132.95):

    • Spring 1988 Volume 1

    • Spring 1988 Volume 2

    • Spring 1988 Volume 3

    • Fall 1988 Volume 1

    • Fall 1988 Volume 2

    • Fall 1988 Volume 3

    • Spring 1989 Volume 1

    • Spring 1989 Volume 2

    • Spring 1989 Volume 3

For Fall 1989, the price was $149.95 (standing orders: $142.95):

    • Fall 1989 Volume 1

    • Fall 1989 Volume 2

    • Fall 1989 Volume 3

For 1990, Bowker had a new deal: receive both the Spring and Fall 1990 volumes for $289.95, or buy either individually for $159.95 each:

    • Spring 1990 Volume 1

    • Spring 1990 Volume 2

    • Spring 1990 Volume 3

    • Fall 1990 Volume 1

    • Fall 1990 Volume 2

    • Fall 1990 Volume 3

The 1991 editions were $169.95 each:

    • Spring 1991 Volume 1

    • Spring 1991 Volume 2

    • Spring 1991 Volume 3

    • Fall 1991 Volume 1

    • Fall 1991 Volume 2

    • Fall 1991 Volume 3

In 1992, Bowker increased the Spring and Fall editions to 6 volumes each! It was $202.00 for the Spring 1992 edition, $182.00 for the Fall 1992 edition, or a yearly subscription for $350.00. Starting with the Spring 1994 edition, the price increased to $210.00. An annual subscription for the Spring and Fall 1995 editions was $395.90.

The publication finally ceased with the Fall 1996 edition.

The three publications below were essentially offshoots of PBIP directed at particular audiences: colleges, high schools, and elementary schools.

Paperbound Book Guide—College Edition (1958-1959) / Paperbound Book Guide for Colleges (1960-1964?, 1970-1975/1976) / Annual Paperbound Book Guide for Colleges (1965-1969)

In early 1958, Bowker announced they would publish a separate subject index directed at universities titled Paperbound Book Guide—College Edition (PW, Jan. 6, 1958, at 30). This publication was intended to be a 64-page index, an "outgrowth of our author-title-subject index, 'Paperbound Books in Print,'" and would feature both a selective listing of paperbacks appropriate for the college classroom and Directory of Sources listing bookstores across the East Coast, Midwest, South, Southwest, and West Coast, from which professors or schools could order the relevant paperbacks. Bowker said they would distribute this publication at their own expense to 100,000 college professors and advertised it to bookstores as being a way to boost their sales.

By the May 5, 1958, issue of Publishers' Weekly, it seems like the plans had changed slightly. On page 13, an article says the PBIP subject index (nowhere referred to as Paperbound Book Guide—College Edition*) had been reprinted and bound as a 42-page booklet and mailed to nearly 100,000 university professors. Instructions provided that professors were supposed to fill out a form with their intended assigned readings and the name of the local bookstore through which the order would be placed and return that form to Bowker's College Paperback Service. That department would then forwarded to the relevant publishers to prepare for bulk paperback orders.

* Although Bowker didn't refer to it as the College Edition in the article, there's some strong evidence it was published under that title. For instance, there's an image from a story on the 1958 top paperback sellers in PW that shows several paperbacks on top of a background showing the winter 1958 PBIP and the spring 1958 College Edition. There are also incidental references to a Paperbound Books, College Edition (Spring 1958) in various articles (e.g., Robert H. Woodward, Harold Frederic: Supplemental Critical Bibliography of Secondary Comment, 3 AM. LITERARY REALISM, 1870-1910 95, 125 ("The Sagamore Press edition of DAMNATION announced in PAPERBOUND BOOKS, College Edition, 1958, was never published.") I can't find any references to issues from years with "College Edition" in the title besides 1958 though, so that could either be the only year it was published or the only year "College Edition" was used.

It's possible there was a title change with the 1959 issue. A note in the front matter of the Feb. 23, 1959, issue of PW, at [3], says the 1959 edition of PAPERBOUND BOOK GUIDE FOR COLLEGES will be mailed in March 1959 to 60,000 professors. This edition "describes more than 2,700 available paperbound books of the 75 publishers who have co-operated to publish this catalog." I've found references in publications on Google Books to editions from 1959, 1960, 1962, and 1965. A couple sources, including the Library of Congress's New Serials, indicate the publication started in 1960. Perhaps Bowker was still testing it out prior to 1960, as that's when the Library of Congress assigned it the LCCN 60-3050 (https://lccn.loc.gov/60003050).

The title would change a few times, going from Paperbound Book Guide for Colleges (1960-1964?) to Annual Paperbound Book Guide for Colleges (1965-1969), then back to Paperbound Book Guide for Colleges (1970-1975/1976).

Paperbound Book Guide for High Schools (1963, 1965), Annual Paperbound Book Guide for High Schools (1966-1969)
LCCN: 66-4094 (https://lccn.loc.gov/66004094)
ISSN: 0570-2577

Bowker announced March 1963 that they would follow up their college paperbound book guide with Paperbound Book Guide for High Schools for publication in April (PW, Mar. 4, 1963, at 44). As PW noted, Bowker distributed copies to some 75,000 high school and junior high teachers for free as well as an unspecified amount to paperback wholesalers that served the high school market. The first edition was a trial issue, although Bowker expected it to be an annual publication.

Despite announcing a 1964 edition at 128 pp. for April (PW, Jan. 20, 1964), it appears that this edition was never actually published. A later record for the 1966 edition, which was the first to bear the new title Annual Paperbound Book Guide for High Schools, indicated that the title had previously been biennial from 1963-1965.

Paperbound Book Guide for Elementary Schools (1966)
LCCN: 75-661 (https://lccn.loc.gov/75000661)
ISSN: --

PW noted in an article on paperbacks in schools (PW, Nov. 1, 1965, at 17-18) that Bowker was planning to publish a selective paperback guide directed at elementary schools (as they had for colleges and high schools). That guide, Paperbound Book Guide for Elementary Schools, arrived in fall 1966 and was distributed for free to elementary school teachers across the country. Individual copies could be purchased for $.50, and quantity lots were available to booksellers as well. It seems possible that this title could have been superseded by the following publication directed at elementary school-age children.

Growing Up With Paperbacks (biennial, 1967-1977)
LC Virtual Card Catalog (1967), LC Virtual Card Catalog (1969)

This pamphlet joined the earlier Growing Up With Books and Growing Up With Science Books in 1967, intended to be a compilation of children-appropriate paperback books handed out by booksellers. They were available for purchase in quantity lots. Images of most editions are viewable in Bowker ads in Publishers Weekly: 1967 (July 10, 1967, at [223]), 1969 (Sept. 1, 1969, at 12), 1971 (July 19, 1971, at 58), 1975 (May 12, 1975, at 72), and 1977 (May 9, 1977, at 34).

Publication History of Paperbound Book Guide for Colleges / High Schools / Elementary Schools

Incomplete information about numbers of pages, paperbacks, and publishers in each edition.

Paperbound Book Guide for Colleges

Yale's catalog lists a few volumes of Paperbound Book Guide for Colleges as having volumes numbers (e.g., the 1962 issue as volume 5). That makes sense, but I can't verify the information without seeing an actual volume.

Selected Paperbacks

In the late 1950s-early 1960s, Bowker encountered a growing problem with the size of the PBIP subject index, as there were more and more paperbacks being released each year, so Bowker had to limit the subject indexes to only new and forthcoming titles. Even when Bowker changed the publication schedule of PBIP from 2 complete issues (with 2 interim supplements) per year to 4 complete issues per year, PW noted that the subject index for fiction books in those 4 issues would only contain new titles "to prevent 'Paperbound Books in Print' from becoming too cumbersome to use" (PW, Aug. 22, 1960, at 43).

This 1961 seasonal subject guide to PBIP, titled Selected Paperbacks, replaced the reprint of PBIP's subject index, "which was becoming too cumbersome and too big to handle" (PW, June 19, 1961, at 64). The first issue, for summer 1961, was 64 pages long and covered over 4000 paperbacks pulled from the latest issue of PBIP. PW says the first issue featured typical subjects like literature or science as well as "categories of special interest to summer readers on gardening, travel, nature, games, etc." Selected Paperbacks was intended to be released quarterly (in June, September, December, and March), with special subjects reflecting each issue's season.

An ad showing the front cover of the summer 1961 issue appeared in the May 15, 1961, issue of PW, at [75] and one showing the fall 1961 issue in the Aug. 21, 1961, issue, at 26. These ads show the summer issue as having a sun logo on its front cover and the fall as having a head of wheat. An ad in the Oct. 30, 1961, issue of PW, at 10, has ordering information for the winter 1961-1962 issue, but there's no other mention in PW of this title. There are, however, copyright registrations in the Library of Congress Catalog of Copyright Entries for the winter 1961-1962 (registered Dec. 22, 1961) and spring 1962 (registered Apr. 6, 1962) editions. I don't think this means these editions were necessarily ever published, but they were certainly planned.
