### 'String too long' in BibTeX

The BibTeX diagnostic "Warning-you've exceeded 1000, the `global-string-size`, for entry `foo`" usually arises from a very large abstract or annotation included in the database. The diagnostic usually arises because of an infelicity in the coding of abstract.bst, or styles derived from it. (One doesn't ordinarily output annotations in other styles.)

The solution is to make a copy of the style file (or get a clean copy from CTAN - biblio/bibtex/contrib/abstract.bst), and rename it (e.g., on a long file-name system to abstract-long.bst). Now edit it: find function `output.nonnull` and

- change its first line (line 60 in the version on CTAN) from `"{ 's :="` to `"{ swap$"`, and
- delete its last line, which just says `"s"` (line 84 in the version on CTAN).

Finally, change your `\``bibliographystyle` command to refer to the name of the new file.

This technique applies equally to any bibliography style: the same change can be made to any similar `output.nonnull` function.

If you're reluctant to make this sort of change, the only way forward is to take the entry out of the database, so that you don't encounter BibTeX's limit, but you may need to retain the entry because it will be included in the typeset document. In such cases, put the body of the entry in a separate file:

>     @article{long.boring,
>       author =    "Fred Verbose",
>       ...
>       abstract =  "{\input{abstracts/long.tex}}"
>     }

In this way, you arrange that all BibTeX has to deal with is the file name, though it will tell TeX (when appropriate) to include all the long text.
