But how to produce such a list in an online bibliography? After all, the aim is not to look for authors and titles one already knows, but to include those that do not turn up in the usual lists and are forgotten. Unfortunately, most online catalogs and bibliographies do not include a separate index for edition statements. Brave scholars among us will use the browse function to look for authors and work through the entire author index of the database, beginning with “a” and ending with “z.” For each entry in the index is indicated how many titles refer to the listed author, but how this index is generated often remains an enigma. Three titles, for instance, are linked to the entry “a, a n” (the initials of Antoine Nicolas Agron). But clicking on all three titles does not explain why his initials appear in this index: all three title pages mention his entire name.

Apart from this difficulty, browsing the entire author index seems to be an impossible task. After twenty screens, one reaches names beginning with “aalst” where we find, among others, the name of Gerardus van der Aalst (1678–1759), who is mentioned in seven titles. At this point, one regrets the fact that online databases do not come with printed indexes. Browsing the title index does not help, either. The STCN claims to describe about 200,000 titles, much more than we are looking for in this particular case.
As the following screen shot shows, titles are sometimes followed by edition statements, which are useful when one tries to compose a list of steady sellers. Take, for instance, the following list:

Interestingly, Het duyfken in de steen-rotse [“The Pigeon in the Rock”] appears four times on this screen, three times as the “fifth enlarged impression”—a clear indication that we are dealing with a popular work. The fingerprint of all three editions is different, which means that the type setting for each of them is different, which in turn suggests that the book was very quickly sold out and immediately reset. The Folger has also a copy of this fascinating work, notably the “fifth enlarged impression” printed by Michiel Cnobbaert in Antwerp.

Edition statements seem to be a valid way to retrieve steady sellers, but unfortunately, the STCN does not allow for browsing or searching edition statements. As the following screen shot shows, the content of the field containing editions statements are not indexed by the system.

Very few users know that one can easily access the list with all indexes, as well as the entire, tagged structure of any STCN title. One can find it by hovering with the cursor just below the little book icon on the left hand side of the description. When the cursor changes from an arrow to a little hand (in bibliographic terminology, a manicule), one can click and obtain the technical information of the record.

Although edition statements are included in the bibliographic records, they are not indexed. But there is another way to extract them from the descriptions. Bibliographic records are highly structured, and in the background, each piece of information is tagged with a four digit number. This is also the case for the STCN. In August 2013 I asked the project management for a download of the entire database as a tagged, plain text document, which looks like this:
Section from the STCN download as a tagged text document. Each field is preceded with a four digit number.
From here, it is only the matter of extracting from this file all fields tagged with the number “4020.” This sounds easier than it is: the entire text file is over 460 MB and counts more than 11,000,000 lines of information. I divided the original file into 20 parts, which I imported in a FileMakerPro database, which seemed to have trouble digesting the original single file. With the help of scripts, I extracted the tags and linked each line to the right record number. As a result of this operation, I found 18,378 out of a total 187,854 records with an edition statement, or 9.7% of all descriptions. In 10,569 cases, a number is mentioned in the edition statement, for example “3rd corrected edition.” As stated before, this dataset also includes about 500 Dutch-language editions originating from the Southern Netherlands.

The graph illustrates the distribution of the editions statements that mention a number. 47% of all statements refer to a second (corrected, enlarged, etc.) edition. Another 20% are third editions, and 10% are fourth editions. Then it gets thinner. Only 14 editions refer to the 20th edition, and in total, 84 editions mention a number between 21 and 97! If you are curious to see what those titles are, you can download this pdf with deep links in the STCN to the descriptions.
But this is only the beginning. Obviously, there are books claiming to be the 97th edition—in fact, the STCN contains four of them—but the 96th, 95th, and so on, editions are not recorded. Although I did not survey this, I have my doubts about the accuracy of these statements. More interesting to me is the question why a title page would mention a number as 97, and not, for instance, 87. Secondly, there are title pages referring to “corrected impression” or “enlarged edition.” Of course, this implies at least one former edition. Is there a distinction between books referring to an edition number, and those that don’t? And then there are the books which aren’t first editions, but which do not refer to the fact that they are the second, third, or later, edition. Probably, those are the real steady sellers: those which do not need the branding.
Almost 4,000 titles with edition statements have the descriptor “Theology,” including Bibles and Bible interpretation, Christian doctrine, church history, Judaism, other religions, practical theology, and theology in general. Those categories make up only about 11% of all the descriptions in the STCN. 38 titles have the descriptor “Catechisms,” and only 5 have the descriptor “Prayer books.” Interestingly, not a single liturgical book bears an edition statement.
As I hope this shows, it might not be easy to explore edition statements, but there are a lot of questions we could ask and maybe answers to discover!
