Elsevier has recently lunched a tool called Journal Finder by which researchers can use paper's title and abstract, and field of study to find a suitable journal for their manuscript. Here is the sample in which the editorial time is 12 weeks. They surely maintain database for their own, but is there any other source we can do this for other non-Elsevier journals, like IEEE or ACM? I know WoS provides some information about it, but WoS's database accuracy is not yet clear to me since I have seen lots of inaccurate information in WoS reports (for instance, number of "review article" published is often inaccurate).
Once a year the Notices of AMS publish the backlog of mathematics research journals containing inter alia the data you are interested in.
The 2012 one is here:
and the 2013 is here :
and both do list some journals in informatics including the non-Elsevier ones (e.g. the Springer's Acta Informatica).
Elsevier has recently launched a new toolbox including lots of useful information about journals. If you visit any Elsevier journal's homepage (I assume it works for all Elsevier journals], you will see the following box there,
Click on it and select 'Speed' link and it takes you to another page like here (example for JNCA journal). The following information let you know the latest turn around time of this particular journal.
Hope other journals start similar approach. Thanks and hope you find this post useful.
Please see the following link Here. However, it is more about psychology and non-engineering journals. I with there was such an repository for CS.
