In most cases the names of songwriters on the sources are incomplete: initial(s) and last name. But now the initials are useless for MB searching.
Example: try to find "L. Campbell" (or "Campbell, L.", etc.). We see 48 pages of Campbell (1186 results) without any regard to "L" as the first letter of name (only as "L."). Without any initial we see only 330 results for "Campbell", so the initial does not help, but quit the contrary.
It would be very useful to have as first results of searching the Campbell who have the first name starting with "L". The search engine should be understand "L." as initial and show firstly not only L. Campbell, but also Lee Campbell, Leo Campbell, Louis Campbell etc.
