Top journals

There is no single database that will search across all the FT50 or Q1 or A8 journals but you can search across the ISSNs. The ISSN is unique to the journal, there may be a couple - one for the print & one for the online versions. 

So use these ISSNs to search on your topic across a number of major business databases - I would suggest ABI, Business Source Elite and Scopus

To search all 50 simultaneously copy and paste the following text into one of the search boxes and  after pasting the above journal list into the search box, use the corresponding dropdown menu to specify that you are looking for the publication field "ISSN"

ISSNs for the FT50:

00014273 OR 03637425 OR 00014826 OR 00018392 OR 00028282 OR 08239150 OR 00129682 OR 10422587 OR 00178012 OR 00904848 OR 10477047 OR 01654101 OR 00218456 OR 00219010 OR 01674544 OR 08839026 OR 10577408 OR 00935301 OR 00221082 OR 00221090 OR 0304405* OR 00472506 OR 00222380 OR 00222429 OR 00222437 OR 02726963 OR 00223808 OR 00251909 OR 07322399 OR 02767783 OR 10477039 OR 01708406 OR 10591478 OR 00335533 OR 13806653 OR 08939454 OR 0019848* OR 01432095 OR 07421222 OR 00920703 OR 15234614 OR 15723097 OR 01492063 OR 03613682 OR 00187267 OR 02726963 OR 15265463 OR 07495978 OR 15265455 OR 10477039 OR 00487333 OR 00346527 OR 1467937X OR 1932443X

You can do this with other lists e.g. ABDC list of A* journals (ISSN included) or you could manually bring this together from a Q1 subject list in Scimago
