Don't keep separate logs for different kinds of flying. Simply because you fly different categories or classes of aircraft, don't keep a separate log for each one. There is no point, it's far from standard, and looks very unusual. It also makes tracking information much more difficult...particularly for an interviewer.
If you fly gliders, balloons, seaplanes, multi engine land airplanes, and helicopters, keep it all in one spot. I do. It's far better to track. All your endorsements, your records, your evidence of currency, etc, is in one place, and this is the purpose of a logbook.
A word on whiteout. Don't use it. Ever. A logbook is a legal document, and whiteout or correction fluid should never be used. Use a single line through your error, and initial the line, then write in the correct information in the adjacent space. But do NOT use whiteout, greenout, or any other material to cover up and hide. It looks unprofessional, gives the appearance of untidiness, and also looks as though one is covering something up.
When an error is made on a legal document, one should not hide the error. Think full disclosure; a logbook is intended to be maintained the same way. One line through the error, and always initial the correction. Don't hide or cover up material; if necessary, just make a new entry. Corrections to logbooks later on should be done in the same manner. Cite page numbers, and what it is that you're correcting, and you can accomplish large corrections on a single line entry in the log. It's discreet and unobtrusive, and looks professional. More imporatantly, it's expected.
