To build this DIY pipe bookshelf, you'll need:

1. Black iron pipes

2. Pipe fittings (elbows, couplings)

3. Wood for shelves

4. Screws or nails for assembly

5. Drill with drill bits

6. Measuring tape

7. Pencil and paper for sketching the design

Here's a step-by-step guide:

1. Measure your wall space where you want to place the shelf.

2. Determine how many vertical supports (posts) you'll need based on the width of your shelving area and desired spacing between posts.

For 6 foot wide shelving, I wanted three supports for each shelf.

3. Cut four pieces of pipe to length: two at equal height for top and bottom shelves, one slightly shorter for middle support(s), depending on design complexity.

4. Assemble the frame using elbows, couplings, and T-fittings as needed.

5. Measure out spacing between vertical posts along floor line drawn with a pencil or marker; mark these points equally apart (e.g., 36 inches center-to-center).

6. Cut four additional pieces of pipe to length for shelf supports: two at equal height like in step 4, one slightly shorter than others depending on design.

7. Attach horizontal beams between vertical posts using elbow fittings.

8. Repeat steps 5-7 until you have the desired number and spacing of shelves.

9. Add wood planks or boards as required to create shelf surfaces; screw them onto frame supports from underneath for added stability.

10. Install all hardware such as screws, nails etc., following manufacturer's instructions before final assembly.

11. Fill any gaps between pipes with pipe dope if necessary for a neater finish.

12. Place finished bookshelves against wall and enjoy your handmade storage solution!
