Should I normalize inconsistent proceedings titles? I work in a discipline where titles of published conference proceedings are notoriously inconsistent.  (Perhaps all disciplines are like this?)  For example, various years' proceedings of the same annual event may be officially titled a dozen different ways:


Proceedings of the First Annual Conference of the Society for Underwater Basket Weaving
Proceedings of the 2nd Conference of the Society for Underwater Basket Weaving
Proceedings of the 1998 Conference of the Society for Underwater Basket-Weaving
SUBW '99: Proceedings of the Annual Conference
Papers from the Fifth International Conference for Underwater Basket Weaving (SUBW 2000)
Society for Underwater Basket Weaving: Papers from the 6th Annual Conference in Ashgabat, Turkmenistan
SUBW 2002: Past Successes and Future Directions
(etc. etc.)


Sometimes the titles aren't even consistent in the same volume of proceedings—different names may appear on the cover and the inner title page!

My question is, where one's publisher expresses no preference on how one's bibliography is formatted, is it better to keep such titles as-is, or to normalize them?  For example, one possible way of normalizing the above entries would be as follows:


Proceedings of the 1st Annual Conference of the Society for Underwater Basket Weaving (SUBW 1996)
Proceedings of the 2nd Annual Conference of the Society for Underwater Basket Weaving (SUBW 1997)
Proceedings of the 3rd Annual Conference of the Society for Underwater Basket Weaving (SUBW 1998)
Proceedings of the 4th Annual Conference of the Society for Underwater Basket Weaving (SUBW 1999)
Proceedings of the 5th Annual Conference of the Society for Underwater Basket Weaving (SUBW 2000)
Proceedings of the 6th Annual Conference of the Society for Underwater Basket Weaving (SUBW 2001)
Proceedings of the 7th Annual Conference of the Society for Underwater Basket Weaving (SUBW 2002)


The disadvantage of doing this is that your bibliography is no longer an accurate reflection of what's printed in the proceedings themselves.  If any libraries hold copies of the proceedings, they may catalogue them under the original titles, so a reader wouldn't be able to find them there by searching for one of your normalized titles.

However, I think normalization has some significant advantages.  For one, it's always clear which conference of which scholarly society you are referencing—something which isn't always the case when using the original titles.  Since many proceedings nowadays are published online only, normalizing the titles could make it easier for readers to find the society's web page, and through it the proceedings.  Nowadays many proceedings can be uniquely identified by ISBN or DOI; including these identifiers in the bibliography makes it less important to faithfully transcribe the title.  Using consistent titles also makes it easier for readers to search your bibliography for references to papers in proceedings volumes of interest, without having to know or remember their original titles.

A third option would be to list both the original title and the normalized version, though I think this is rather cumbersome, particularly when the two versions differ only slightly.

Am I missing any more advantages or disadvantages?  Do any popular style guides speak to this issue?
The Conference on Precision Electromagnetic Measurements (CPEM) is one conference in my field that suffers from the same problem, complicated by the fact that the proceedings are called conference digest, instead (digest is put sometimes at the beginning, sometimes at the end). I have never seen works from this conference cited in the same way, and given that this conference started in 1962, if there were serious problems in finding the proceedings in the libraries, probably some form of standardization would have come out along the years.

In general, I try to be consistent, at least within a paper. Your example, composed of both the full and the abbreviated titles, seems fine to me: in any case it gives the reader, even one not familiar with your field, all the possible search keys to identify the volume (and one familiar with the conference would probably not care anyway).
