IT IS timely that, three days after the school supply source Extras for Creative Learning was forced out of the space it was using at Boston Latin Academy because of permitting and fire code concerns, the Globe acknowledges that teachers provide for their students out of their own pockets (“Budgets cut, teachers dig deeper for supplies,’’ Page A1, Sept. 5). ExCL is a great program that provides its members from BPS and surrounding communities access to recycled materials to use in educational programs. Discards from various sources are picked up by ExCL and offered to members at a minimal yearly cost, saving the environment from needless waste. In the past year, I have saved more than $2,900 in materials by going to ExCL on only six visits.
