The staff here at HirschMusic world HQ are hard at work to make this website easier to browse for folks looking for sheet music — be it free or premium. Admittedly, this website biz is quite laborious, even with a slick system like the SquareSpace we're presently using.
A "duh-what-took-so-long" improvement is a thorough catalog which lists all available premium titles, their prices, sound clips, and add-to-cart buttons. CHECK IT OUT HERE.
On the horizon are better indexing and browsing interfaces to make it easier to find the sheet music you're seeking. The only deadline we're promising is as-soon-as-we-can-get-it-done.
I always like to hear from you. Feel free to send me your ideas/suggestions.
