Modern Logo for ERE Nonprofit -- 2

I need a modern, clean logo for Educational Resource Exchange (ERE), a nonprofit that supplies educational materials to students and schools locally, nationally, and internationally. The mark should feel contemporary and professional while still reflecting learning and global reach.

Key creative cues
• Work in either stylised books, other educational items, or an abstract symbol that hints at knowledge exchange.
• Keep the design uncluttered—simple lines and balanced typography are preferred.

What I expect from you
1. Two or three strong concept directions, presented on both light and dark backgrounds.
2. A refined final logo delivered in vector format (AI, EPS, SVG) plus PNG and JPG exports, including a one-colour version for stamps or embroidery.
3. A brief style sheet that lists colours (CMYK/RGB/HEX) and the fonts or custom lettering used.

Please highlight relevant experience creating modern logos for nonprofits, schools, publishers, or similar organisations when you apply. I value clear communication and timely turnaround; one revision round is included so we can polish the chosen concept. If you have any questions about the organisation’s mission or visual preferences, feel free to ask—looking forward to seeing your ideas.
