So I tried it and here's what happened.
Out of nearly 50,000 seforim I had to pick one. Not such an easy task, but I finally settled on Pene Tevel (Amsterdam 1872) by Moses Mendelssohn of Hamburg, not as well known as his nephew Rabbi Samson Raphael Hirsch. This is a very important and frankly quite delicious book, and a post about it will be forthcoming. I really wanted a copy, but it also didn't hurt that the pdf isn't exactly high resolution, and the font is quite small. So if it returned a readable and pleasing result that would be all the better.
First I will go through the process as I did in the EBM post. When you're on a book's page, click the link, as below:
Since PublishYourSefer.com has already processed this book because of my order, the page you would go to now has a copy ready for order. So I will show a different page, which was essentially what I saw, only for the Pene Tevel:
As you can see, it gives an estimated price quote for the soft and hardcover versions. In addition, there is a link at the top explaining how you can find Lulu.com coupons and possibly save money on your order, All you have to do is enter your email address and fill out the captcha, and hit Submit Print Request. You will get an email confirmation, and relatively quickly more emails informing you that the hardcover and softcover versions are available for purchase. It should be pointed out that there is no obligation to purchase whatsoever, so sending a request like this costs nothing. Whether or not you purchase it, all it means is that in the future someone else will not have to wait for the processing time.
It was known to PublishYourSefer.com and HebrewBooks.org that I was going to review the process, so you'd expect PYS to provide the very best service in this case, but I had prepared books this way in the past, only I never ordered them. So having experienced the preliminary stage of ordering without any special treatment, I can't say that there was much of a difference in how long the confirmation was received. I feel that my experience this time was probably fairly representative. It must have been a few hours until the books could be ordered.
The processing time estimated by PublishYourSefer.com on the site is that it will "usually take about 1-3 weeks." But I am informed that 1-3 weeks is an old estimate. Now 24-72 hours is to be expected. As you will see, his estimate was accurate. In less than a day I could order it, and from start to finish I received the books in almost exactly 1 week.
When the processing is completed, I received an email telling me that the book could be ordered, and was sent the following link:
As you can see, the price estimate was off by a little. Instead of $7, the softcover was $8.99. On the other hand instead of $19 - $21 the hardcover was only $16.99. Obviously there is also a shipping cost, but at this point it's in Lulu.com's hands. They offer the usual range of shipping options to be expected. An advantage here, missing in the EBM purchase, is that the size of the books is specified. In addition a 50 page pdf preview is provided, so you can get a sense of whether it processed properly. I'm told that Lulu.com will refund the money if it messes up the printing. Note that there is a page listing all books that have already been processed, which is updated hourly, and those in middle of being processed (link). It's worthwhile having a look.
From start to finish - my order was processed on Monday October 10, and I received it on Monday October 17. To give more precise details, Lulu.com confirmed the order on Tuesday 10.11, and that it was shipped on Thursday 10.13.
Here is what I received:
Please note that the poor quality of the photos is only to demonstrate my lack of skill as a photographer. In fact both books printed very nicely. The only difference was that the hardcover printed on a very white paper which was a little less nice than the softcover, which printed on a more cream colored paper that was pleasing to my eyes. Paper stock was fine in both cases. Both bindings were excellent - in fact superior to the EBM product (which is certainly very adequate).
I must reiterate that what you will get is only as good as the pdf. If it is missing a page - as this book was - then obviously a page will be missing. It is the purchaser's responsibility to ensure that they go through it and know what to expect. In some cases there may be ways of repairing a pdf. PublishYourSefer.com told me that the system is highly automated and there really isn't a lot of ways of tweaking it on his end. In addition, it basically operates at cost for him - as you'd imagine, there can't be much profit in a $8.99 book, which mostly goes to Lulu.com. There is another division with greater flexibility, which is why it is called PublishYourSefer.com. So he informed me that if you could fix the pdf, say, ordering the page correctly, or adding a missing page, etc. then the thing to do is to notify HebrewBooks.org and submit the corrected pdf, and then order it once that is posted. All in all most reasonable.
So what's the bottom line? There's nothing to complain about. It's possible that EBM's prices are a bit better. If that's the case, then if you see a volume of the Aruch Hashalem that you want to print, by all means go through Google. But for tens of thousand of seforim which are on HebrewBooks.org but not Google Books - there is every reason to feel confident about using PublishYourSefer.com reprints (via Lulu.com ). It would be too much flattery to give it more than the 8 out of 10, which is what I rated EBM, but I'm almost tempted to give it a 9 simply because of how impressive it is that a small business with much creativity and technical prowess can produce a result as good as a much-hyped invention partnered with a corporate entity almost as ridiculously limitless as its namesake, the number googolplex.
