Thomson Reuters have recently introduced a new tool called Match as part of EndNote online. You can type in your title and abstract and also select a group of references you used for the article if you have them in EndNote. The search will work without references if you don’t. It will then try to match you to appropriate journals and will produce a list including the impact factor of the journal.
Elsevier have a similar tool called Journal Finder http://www.elsevier.com/journal-authors/home. It does seem to be restricted to Elsevier journals but gives some helpful information such as the % of articles accepted and production times.
CoFactor Journal Selector http://cofactorscience.com/journal-selector takes a different approach, asking you questions such as subject area, type of peer review and open access you are interested in, how quickly you want the paper published etc.
Journal Guide https://www.journalguide.com/
This is aimed at all subjects and includes the experiences of others who have published with the journal as well as other factors. It gives journals a score based on SNIP (Source Normalized Impact per Paper), a similar type of measure to impact factor.
JANE (journal/author name estimator)
For those in the medical field JANE http://www.biosemantics.org/jane/ will match your abstract and title against information in Medline.
Obviously these are only starting points to give you ideas. If you need more information about a journal Ulrich’s International Periodicals Directory can be helpful. Amongst other things it will tell you if a journal is peer reviewed and which services index it – a long list of abstracting and indexing databases is usually a sign of a quality journal.
If you have tried any of these tools or know of any others please share in the comments.
