Hi @Einar Saukas , it seems there's a problem in the Microhobby folder.

Whenever I click on [PDF] works ok (the PDF file is shown) but if I click on [VIEW] a new archive.org screen appears with the next error message:

'The item you have requested has a problem with one or more of the metadata files that describe it, which prevents us from displaying this page'
That's a problem at Archive.org. I will try to find a different source. Thanks for reporting it!

Besides, in the list of Microhobby issues, before #1 issue some random issues appear (with no corresponding picture):

1985/10
1987/3
1987/7
1991/4
1991/5
1991/12
These are "lost issues".

For instance, according to Martijn's WoS there was a reference to game "Combinatoria" in MicroHobby year 1985 month 10 page 9. The problem is, MicroHobby was a weekly magazine, therefore several issues of this magazine were published in October 1985. Which one of them contained this reference?

I have fixed literally thousands of these reference problems in ZXDB, but I didn't notice MicroHobby still had a few problems left. I will fix them all, thanks for reporting it!

I'm planning to remove column "is_electronic" from table "magazines" in the next ZXDB update.

This column is supposed to distinguish between paper and electronic magazines. However it's more informative to simply obtain this information directly from the magazine format: PDF for paper magazines, TAP or TZX for tape magazines, MGT or DISK for disk magazines, etc. In particular, I know SpectrumComputing is already doing it.

Moreover, I had identified a few cases where column "is_electronic" conflicted with the magazine format. In all such cases, "is_electronic" was wrong. I could have fixed these values, but there's no reason to keep a column that's redundant anyway.

I'm announcing this change in advance, to give site owners the chance to let me know if this change would affect them.

I'm also planning to remove columns "link" and "link2" from table "magrefs" in the next ZXDB update.

This information will be moved to a new table, because it's technically a one-to-many relationship.

A new ZXDB version is already available!

This update contains lots of updated information about magazines. I will talk about them in further detail after SC is updated with this new version, because it will be easier to describe these changes when users are able to see them in practice. :)

Another ZXDB update is available!

This update includes lots of minor changes, such as the notion of "derived" titles. It refers to a new title that is basically an improved version of another title from the same author (for instance see this thread). I will start a new thread later to discuss about it in more detail...

I have just started this new thread about it.

A note for site owners running ZXDB:

In the ZXDB update, I'm planning to remove column "hardware_feature" from table "entries". The reason is, this column currently contains website links, so it's more appropriate to store this information in table "webrefs" instead.

I have been so focused on improving ZXDB, that I forgot to take some time off to document and explain the ZXDB roadmap. My apologies!

Our current and future plans for ZXDB are now documented here:

https://docs.google.com/document/d/1o_f ... sp=sharing

I wrote is as a separate online document because I intend to update it over time. In particular, I probably forgot to mention a few important items that I will need to add later. :)

Feedback is welcome!
